Fluctuating brightness: Has this Fluctuating brightness problem been fixed?
13824
We bought ours during Thanksgiving from Best Buy and we do not have the fluctuating brightness problem. I don't remember the date, but I read in one of the reviews about when this problem was fixed. You will have to see the date on the box when you buy it because if the box has been sitting in the inventory for a year then you will have the one with the fluctuating brightness. There is also a fix for this fom Panasonic apparently. Hope this helps!

I've had mine running 8-9 hours a day for the last two weeks, plus lots of time since my review. No brightness issues that I've noticed. The cause of the diminished brightness in LED products, especially cheap ones, is that the designers intentionally over drive the LEDs to increase the brightness. This also shortens the life of the LED.

I have the flicker with mine with YouTube and other video sources as well. Not sure what the problem is yet but I'm looking into it.

You have to turn off the Light Sensor and Dynamic Backlight first, then it will let change the brightness.

Never had a problem with brightness. Make sure you check your settings, some will make the picture dimmer. Also make sure the mirror inside the set is clean.

I have more of a backlight issue when viewed from off angle. There is a white fuzzy band of excess brightness on the right 1/8 of screen, that washes out the color. is this similar to your set?

I didn't have that problem but there was a glitch in mine which made my screen flicker. I believe that it's a manufacturing issue. If you can't get it to work, is send it back and ask for another one

If I turn the brightness down far enough, then PWM flicker does show up, but I run it at 100% brightness and haven't had any problems. From what I have read, running the brightness at 100% eliminates the use of PWM. People suggest using software to adjust brightness and leave this at max.Mine has 5 buttons on the bottom of the monitor, from left to right, Bright+, Bright-, Vol+, Vol-. There is no display showing you what setting you are at though.

How can you adjust the brightness when the brightness option is shaded out on the setup menu? Help!

I have the same model (LED) and am coming up on having it 18 months. Hope I dont have the same problem. My son got the DLP (not LED) lamp model, 61" I believe, and has had no problems with his yet in the same time frame. I have noticed a picture "jitter" and rainbowing effect on some movies.

There's a setting that changes the brightness according to ambient light levels. I suggest leaving it off all the time

Yes. There are three levels of brightness. The brightest one is almost too much. I use level 2.

Try turning the brightness down and the contrast up and also adjust the color so it looks as real as possible. Also you can change the energy saver setting to make to lighter or darker. Offhand my settings on dynamic mode are: Contrast: 95 Brightness: 32 Color: 64 Sharpness: 90 Energy Saver: Level 1
